UNITED STATES PATENT oFFicE mum-r1. AND nnvrs manner mwm, or men Home, 7 c LONDON, momma @NS'I'BUCTION OF ROOFINGS, PAETITIONg, AND. THE LIKE Application flle'd Kay 81, 19 80, Serial No. 458,818, and in Great Britain September 5, 1913b.

This invention relates to the construction of roofings,lpartitions and the like and the main object of the invention is to provlde metal sheets or anels, adapted to be secured to the purlins o the roof or to battens or to corresponding members in the construction of partitions, walls or the like having a substantially flat surface which may thereafter be treated as,fo r instance, by the a pl cation thereto of bituminized felt or of exible roofing material in sheet form. t

The invention consists, broadly, in a substantially flat sheet or panel provided oneach of two of its opposite sides with aflange whereby it may be interlocked or interchanged with similar sheets and with reinforcing ribs generally parallel with the said flanges extendin beyond one edge of the sheet or panel a apted to mterengage with the reinforcing ribs on a similarly formed adjacent sheet or panel; a

Thus in accordance with the invention the main portion of the sheet may be substantially flat with a plain flange on one of its sides the surfaceof which extends at right angles with the main ortion of the sheet or panel and'a flange on t e opposite side of the sheet or panel arranged with an upturned edge forming a recess in which the plain flange of an adjacent sheet or panel may be engaged and a plurality "of reinforcing ribs extending the length of the sheet or panel parallel with the anges and projecting beyond one end of the sheet or panel to form projections adapted to engage t e reinforcing ribs of an adjacent sheet or panel Conveniently, the ,reinforcingribs are in the form of channel members of sheet metal secured, for instance, to the body of the sheet 40 or panel by welding or other suitable method of connection, the adjacent ends of the channel members extending beyond one edge of the ribs may be expanded suitably in order that in them may be engaged" the ends of the ribs substantially flush with one edge of an adjacent sheet or panel.

Conveniently, the reinforcing ribs, when of channel section, are flanged for the greater portion of their length to assist in securing connection between them and the main portion of the sheet or panel..

Preferably, the reinforcing ribs at points adjacent to the edge of the sheet or. anel with which the ends of the ribs are fius are provided with holes through which hookolts, screws, or the like may bepassed for the purpose of securing the sheet to apurlin or likestructural member and to facilitate securing the sheet or panel in position, holes may be provided in the material of the sheet or panel through which a screw-driver, boxspanner or the like may be introduced to facilitate fastening the sheets or panels in position. x

Normally the depth of the ribs and of the flanges on ,the sheets or panels will be equal; I

The invention also extends to roofings, partitions, walls and like constructions including a fiat sheet or panel as defined above.

When material in accordance with the invention is employed in the construction of roofing a plurality of sheets formed as abovedescribed are laid up in position on the roof purlins and secured thereto 1) hook-bolts, screws, nails, or the like passe through the holes provided in the reinforcing ribs after which the external surface of the roof so formed is treated in order to render the same 5 impermeable to water. I 1 y Thus, for instance, to the surface of the sheets may be applied flexible-roofing material such as bituminized felt.

In some-casesit may be found convenient to form the reinforcing ribs integral with the main portion of the sheet or panel but generally it may be stated that it is more convenient and cheaper to. form the ribs separately from the main portion of the sheet or panel by, for instance, pressing them from sheet material 7 and subsequently securing the ribs thus formed to the main portion of the sheet or panel by a welding operation. The invention will be described further in detail and by way of example with reference to the accompanying drawings in which Figure 1 is a lan view illustratin the construction ofa s eet or panel in accordance with the invention,

In the drawings 1 indicatesa substantially flat sheet or panel having on one of its sides a plain flange 2, the surface of which extends at right angles with the main portion of the sheet or anel, and'a flan e 3 on the opposite side of the sheet arrange with an u -turned edge forming arecess 4, in which t e plain flange 2 of an adjacent sheet or panel may be engaged, and lengthwise of the sheet or panel parallel with the flanges, is rovided a plurality of reinforcing ribs 5, t e ends. of which at one end of the sheet or panel project beyond the edge of the latter to form projections 6. adapted to engage the ends 7 of the reinforcing ribs of an ad acent sheet or panel. The reinforcing ribs 5 are in the form of channel members of sheet metal secured to the body of the sheet or panel by welding .or other suitable method of connection, and are also. formed so as to provide a spigotand-socket joint between ends of adjacent sheets or panels, and to this end the project ing portions 6 are formed relatively smaller in effective cross-section than the portions 7 of'the ribs of an adjacent sheet which they are adapted to engage, and the ends 7 of the ribs are also extended for the same purpose. In order to assist in securing connection between the reinforcing ribs 5 and the main portion of the sheet or panel, flanges 8 are 7 provided on the ribs adapted to be welded, soldered, or connected in any other suitable manner to the sheet or panel, and the ribs are provided in the portions 7, see Figures 1 to 4, with holes 9, and in. the projections 6 with holes 10 through which hook-bolts 11 or other suitable fastening means may be the projections 6 of the sheets engaging within the portions 7 of adjacent longitudinally disposed sheets, and are secured to the purlins, see Figures 4, 5, 6, 7 "and 11, by means of hook-bolts 11. I

To the surface so formed is applied a layer of insulating material 13 and a layer or a plurality of layers 14 of bitumini-zed felt or like flexible roofing material, the insulating material being secured in position on the sheets, see Figures 6 and 7, by means of cleats 15 engaging therewith and secured to the hook-bolts 11, the points-of the cleats being hammered down-level with the surface of the insulating material.

In the treatment of the ridge of a roof as illustrated in Figure 5, a ridge plate 16 is located on and extends over the edges of the adjacentisheets and a strip of flexible roofin material-17 is arranged, as shown, to provide a weather proof sealing at the edge of the ridge.

In the trough or valley construction illustrated in Figure 8, the sheets or panels are secured to the purlins adjacent to the edges thereof by means of the bolts 18, which bolts also serve to secure in position the valley cover stri 19 upon whichis disposed a light concrete fllling 20; the insulating material and the flexible roofing material being con-- tinued unobstructed over both roof surfaces and the surface of the filling.

In a trough or valley treatment at the junction with a wall of a roof surface as shown in Figure 9, the layer of insulating material is continued to the wall surface, a filling of light concrete 21 is laid thereon in the trough or valley, and the layer of 130 roof material onthe w inforced by means of flashing 22 composed sides 0 faces comprislng flanges whereby the sides of 65 panel above flexible roof material is continued from the roof surface over the surface of the filling and for a suitable distance over the surface of the wall,.that

surface being reof flexible roofing material secured in position b means 0 lead wedges or any other suitabe means. i

In the treatment of the ridge of a roof if g}? so-called saw-toothtype, illustrated sheet covering the upper surface, being located between the layer of insulating material and the surfaces of the sheets or panels adjacent to the edge of the roof.

to which flexible roofing material ma applied and while. the'main utility o the invention is perhaps to be found in the col struction of roofs it will be understood that sheets or panels accordance with the inventionv mayfbe laid up to form a vertical or inclined structural member other than a roof such, for instance, as artitions, party walls, or the main walls 0 and like structures.

We claim: 1. A substantiall flat panel'of rectangular form adapted or use on structural surfaces comprising flan es whereby the sides of the anel may be interengaged with the F adjacent similarly ormed panels, reinforcing ribs generally parallel with the said flanges extending beyond one edge of the pane, and apertures in the said ribs adapted to accommodate a fastening member lfgr securing the panel to a. structural mem- I. v 2.
